A method and system for monitoring performance of an input/output (“I/O”) processor in a server associated with a computing system, such as an intelligent I/O (“I2O”) compliant computer system. A virtual adapter in the I/O processor monitors messages passing through the I/O processor to produce message data. An I/O monitor associated with each server in the computing system constructs a server communications model for its respective server using the message data provided by each of the virtual adapters associated with the I/O processors in the server. The I/O monitor may also collect information regarding non-I2O devices. An I/O user interface builds a computing system communications model using the server communications models provided by the respective I/O monitors in each of the computing system's servers. The I/O user interface provides selectable views for the computing system communications model and the server communications model for each of the servers in the computing system. The I/O user interface also provides controls for adjusting the operating characteristics of the virtual adapters in the I/O processors and for adjusting operating characteristics of the I/O monitors in the servers. The virtual adapters are visible throughout the computing system by appearing to the other components of the computing system as disk drives.
